Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. Nosowska 1997 | Outer face of marginal ossicles densely covered by tubercles: superomarginal tubercles very small, of equal size; inferomarginal tubercles differentiated into smaller ones, ball- or horseshoe-shaped, and bigger ones, always horseshoe-shaped, spaced in variable number along the abradial margin (at least two at one arm ossicle) and the distal margin; tubercles make a basis for large, strongly flattened scales (the largest are of the length equal to the width of the ossicle they grow on); adambulacrals with relatively long, sharp spines. |
